【 摘 要 】

Floor water disasters have occurred frequently, which can be treated by grouting and reinforcement of floor. The purpose of this paper is to study on time-dependent viscosity of slurry and its diffusion model for guiding grouting and reinforcement engineering by observing of the change of slurry viscosity with time in laboratory. The result showed that the slurry viscosity had an exponential trend with time. A slurry diffusion model based on the time-dependent viscosity of slurry is derived, according to the diffusion model of grouting in horizontal single fracture under hydrostatic condition. These results will provide theoretical basis for grouting process adjustment and regional grouting transformation.
